FIELD: physics.
SUBSTANCE: measuring consists of a section of a conduit with two dielectric slit-type windows, microwave generator, connected to a series of two sensors of power incident on the stream and a sensor of power reflected from the stream, sensor of power passing through the stream, mixer, device for input and device for output of microwave energy into/out of the conduit, in the form of a directional coupler circuit with tight coupling, two amplitude detectors, microprocessor and display. The slit-type dielectric windows are coupling apertures in the energy input/output devices and are located up along the conduit section. The primary line of sensors of power through the stream and secondary line of sensors of power incident on the stream and the sensor of power reflected from the stream are connected to ballast loads.
EFFECT: increased sensitivity of the measuring device and simplification of the structure of the device.
